How you'll revise IB Diploma Biology
Start with the map
Every IBDP-BIO statement is already broken out, so you can see the whole syllabus. Exam-style hinge questions are being added topic by topic.
Find your misconceptions
Each wrong answer reveals the precise misconception behind it — not just a red cross.
Correct on the spot
A targeted correction step fixes the exact mistake while it's fresh.
Lock it in
Spaced repetition brings weak points back until every statement turns green.
Lessons for every syllabus point
100+ guided lessons cover the full IB Diploma Biology syllabus — one per statement. Read the explanation, test your understanding, then go into the question bank knowing exactly what each statement is asking.
Explanation first
Each lesson opens with a clear, concise explanation of exactly what the syllabus statement requires — no more, no less. You always know what you're being asked to know.
Checks for understanding
Embedded questions interrupt the lesson at the key moment, while the material is still in front of you. Low-stakes, immediate feedback — so you catch gaps before the question bank does.
Interactive diagrams
Many lessons include diagrams you can manipulate — label a structure, drag a particle, adjust a variable. Building the concept in your hands beats re-reading it every time.
Simulations
Some topics include a full simulation: change a condition, observe what happens, explain the result. Designed so you can't just memorise an outcome — you have to understand the mechanism.
Lessons are available free inside the app — sign up to access them alongside the question bank.
IB Diploma Biology revision — your questions
Does PinPoint follow the new IB Biology guide for first exams 2025?+
Yes. PinPoint is built around the current IB Diploma Biology guide, organised across four themes (A–D), with every understanding turned into exam-style multiple-choice questions.
Does it cover both SL and HL Biology?+
Yes. Standard Level and Additional Higher Level content is tagged separately — SL students only see SL content, HL students see both.
Can PinPoint help with IB Biology Paper 1 multiple choice?+
Directly. PinPoint's questions are exam-style multiple choice with distractors built from real misconceptions — the same skill Paper 1 tests.
